13058 search makes resolve go slow
This webrev cuts the time to resolve ON from 4:30 to about 15 secs.
The memory used goes from about 110M to about 180M.
I tested this on x86 and get similar results. (Hoping to test on
sparc later today, but I'm not sure I'll have the chance to get the
environment set up.)
The code looks reasonable to me, but I'm hardly an expert.

As a follow up, Liane and I both tested this on sparc.
Using the gate bits, she found resolve took 17 mins with the old
version, and 33 secs with the new one.
I killed the gate bits after 25 mins, which the new version took 2:46.
On a second run which finished in 2:40, about 2:13 seconds was spent
loading the various manifests, once that was done, resolving the
dependencies took 13 seconds. It's possible that loading the manifests
could be parallelized on sparc for extra speedup since the processor was
essentially pegged the entire time. I'll leave that as another bug
though in the interest of getting this back now.
